And in the sense of this relief he fell asleep, and dreamed that he stood again at Mrs. Forrester's door in the Isle, and saw the light on the old tower of Kinloch Houran, and felt the attraction, the drawing and dragging as of some force he could not resist; and woke up with the blow he gave himself against the rail that supported the netting on the opposite side of the carriage, against which he struck his head in his rush towards the place to which he had felt himself called. He staggered back into his seat, giddy and faint, yet thankful to feel that it was only a dream; and then had to begin his self-arguments over again, and trace once more every link of the chain. A monomaniac--yes, that might be the explanation; but whence then that power which drew him, which he had fought against with all the powers of his being at Auchnasheen, which he had never given in to, but which, even in the reflection of it given in his dream, was vivid enough to awaken him to a new branch of the question? Magnetism, mesmerism, he had heard of, and scorned as other names for charlatanism; but when you are searching anxiously for the means of accounting for mysterious phenomena you are glad to seize upon explanations that at another moment would be little satisfactory. Walter said to himself that the madman of Kinloch Houran--the monomaniac, must possess these strange powers. He might know many secrets, though his wits were gone astray. He might be sane enough to have a purpose, and to cultivate every possible means of affecting the mind he wished to work upon. Such curious combinations of madness and wisdom were not beyond human experience. Perhaps at the end of all his arguments, having fully convinced himself, the thread of the reasoning escaped him, for he suddenly shuddered and grew pale, and shrank into his corner, drawing his wraps close round him and raising the collar of his coat to his very eyes, as if to shut out some bewildering, overwhelming sight. But by this time the wintry day was breaking, and the stir of awakened life reached the other travellers, who woke and stretched themselves, shivering in the chill of the dawn, and began to prepare for their arrival. One of them spoke to Walter, expressing a fear that he was ill, he looked so pale, and offering his services to "see him home." The young man indeed felt as if he had come through a long illness when he stepped forth upon the platform at King's Cross, and felt that he had escaped from his fever and his trouble, and had new ways and new thoughts--or rather the repose of old thoughts and old ways--before him for some time to come.
